Table:

Predictive Value of POA=N and POA=Y for Hemorrhage diagnoses

Diagnosis/POA combination	Coded POA=N (n)	% HA Hemorrhage (95% CI)	Coded POA=Y (n)	% Hemorrhage PTA (95% CI)
Overall	166	85% (80%–90%)	209	86% (82%–90%)
Type of Hemorrhage
GIB	95	84% (76%–92%)	109	83% (75%–91%)
ICH	71	86% (78%–94%)	100	89% (83%–95%)
Anticoagulation Status
Taking AC*	25	23/25: 92% (82%–100%)	38	33/38: 87% (77%–97%)
Not taking AC	134	84% (78%–90%)	165	88% (82%–94%)
Sites
Site 1	90	83% (75%–91%)	118	90% (84%–96%)
Site 2	76	87% (79%–95%)	91	80% (72%–88%)

POA = Present on Admission. HA = Hospital Associated. PTA= Prior-to-Admission. 95% CI = 95% confidence interval GIB = Gastrointestinal Bleed. ICH= Intracranial Hemorrhage. AC=Anticoagulation
